Description

This is a kit to build a dual 9 way D joystick interface for the Commodore PET and Mini PET Userport.

This is constructed with through hole parts (included). The diodes are used to generate the fire signals, and the resistors protect the userport if it is configured as an output.

The value read is the position information from a standard Commodore / Atari style joystick with the usual pinout:

    • 1 = Up
    • 2 = Down
    • 3 = Left
    • 4 = Right
    • 5 = N/C
    • 6 = Fire
    • 7 = N/C
    • 8 = GND
    • 9 = N/C

 

There is no power on the userport of the PET, so no autofire etc. 

The value is read from port E841 (59457), and is best calculated using 255-PEEK(59457).

The values returned from this are as follows:

    • 0x01 (1) = Port 1 Up
    • 0x02 (2) = Port 1 Down
    • 0x04 (4) = Port 1 Left
    • 0x08 (8) = Port 1 Right
    • 0x03 (3) = Port 1 Fire
    • 0x10 (16) = Port 2 Up
    • 0x20 (32) = Port 2 Down
    • 0x40 (64) = Port 2 Left
    • 0x80 (128) = Port 2 Right
    • 0x30 (48) = Port 2 Fire
